This can be repeated many times before the editor crashes without any messages and other programs with the video driver crashes too. Because out-of-memory.
This is similar to [Link Removed].

This was reported and tested in 4.24.3 (CL-11590370). This was reproduced in 4.25 (CL-13144385) and Main 4.26 (CL-13230104)

Steps to Reproduce
  1. Open the UE4 Editor and create a Blank project
  2. Open 'Editor Preferences' and in the Performance section, enable the 'Show Frame Rate and Memory' option
  3. Place the Editor Preferences tab in the main editor window. See repro video.
  4. Remember used amount of memory and press Simulate and then stop Simulating

Results: Memory usage increased by 200-500MB each time you Simulate

Expected: Return to previous value of used memory by editor
